FeatureFactory is a web application built on top of JupyterHub and an accompanying Python package that together facilitate collaborative data science efforts as well as data collection experiments on those efforts.
The FeatureFactory Python package is used to administer a data science collaboration. It allows users to "register" features in a database backend and discover features written by other users. These features are automatically scored by the system so that users can see realtime feedback on the quality of their features.
The FeatureFactory app includes a JupyterHub server, containerized Jupyter notebooks for each user with the FeatureFactory package installed, a database backend to store the features, and data- and user-management tools.
